London: "Harry Potter" star Daniel Radcliffe, set to go naked for his new film "Kill Your Darlings", says he is comfortable with nudity.

The actor first stripped off for psychological drama "Equus" on the West End stage.

"I'm comfortable with my body," Radcliffe told a magazine.

However, the actor also admits he will never be able to compete with "Harry Potter" co-star Rupert Grint's muscular body.

"I'm not going to try to compete with Rupert on the arms front. His dad is a big guy, so if anyone was going to get the proper muscleman build, it was Rupert.

"You'd have to search pretty hard to find a more handsome ginger. He's also a dude. I wish I could be that calm. I'm lucky to have found an industry where this level of hyperactivity is encouraged. Otherwise I'd just be a f****** nuisance," he added.
